CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Phosphorus oxybromide appears as a colorless crystalline solid or liquid if heated above 133 °F with a pungent odor. It is commonly heated and shipped in a molten state. Soluble in water, but, decomposed by water to hydrobromic and phosphoric acid with evolution of heat. Reacts with organic materials to cause fire. Evolves highly toxic and corrosive gases when exposed to fire. Corrosive to metals and tissue. Used to make other chemicals. |
